How to Install Windows 11 from a Bootable USB

This guide explains how to create a bootable USB drive to install or reinstall Windows 11 on your computer.

Why do this?

While most people upgrade to Windows 11 directly from Windows 10, some prefer a “clean install.” This wipes your old system settings and files to give you a fresh, glitch-free start. It is a great way to fix performance issues or prepare a used computer for a new user.

What happens when done?

You will have a portable USB drive that can start up a computer to install a brand-new copy of Windows 11. Your computer will be reset to its factory-fresh state.

Creating the Installation USB

Microsoft provides a tool to make this process simple. You will need a blank USB drive with at least 8GB of space.

First, download the official tool on a working computer using this link: Download Windows Media Creation Tool

Note: You must have administrator privileges to run this tool. %%SC0%%

1. Run the downloaded tool.
2. Select Accept if you agree to the license terms.
3. Choose Create installation media for another PC and click Next.
4. Pick your language and the 64-bit version of Windows 11.

Next, choose your media:

• USB flash drive: Plug in your 8GB (or larger) drive. Everything currently on the drive will be erased.
• ISO file: This saves a file to your PC that you can burn to a DVD later.

1. Select your USB drive from the list.

1. Click Next to start the download. The tool will prepare the USB drive for you.

1. Wait for the process to finish.

How to Install Windows 11

Once the download is finished, take the USB drive to the computer where you want to install Windows 11.

1. Plug the USB drive into the computer.
2. Restart the computer.
3. If it does not start from the USB, you may need to open the “Boot Menu” or BIOS settings. This usually involves pressing a key like F2, F12, Delete, or Esc as soon as the computer turns on. Check your computer manufacturer’s website if you are unsure which key to press.
4. Follow the on-screen instructions for language and keyboard settings.
5. Select Install Windows.
6. Once finished, remove the USB drive and log in to your new system.

Summary

Using the official Media Creation Tool is the safest way to prepare for a Windows 11 installation. A clean install is the best way to ensure your computer runs smoothly and is free from old errors. Always back up your important files before starting, as a clean install will erase your data.
